11 Claims, No Drawings N-(SUBSTITUTED PHENYL)-2,3-DIAZAB]CYCLO[2.2.21OCT-5-ENE AND [2,2.1]HEPT-S-ENE,2,3-DICARBOXIMIDES The present invention relates to dicarboximides, a process for their manufacture, and to their use in pest control.

The dicarboximides have the formula N/C\ l Ix (I) HN-'C (Y) (II) in the presence of an oxidant with a compound of the formula in which X, Y, and m have the meanings given for the formula 1.

As oxidants there can be used, for example, N- bromo-succinimide, hypohalites, e.g. hypochlorites (tert. butylhypochlorite), nitric oxides, e.g. dinitrogen tetroxide, peracids and salts thereof, e.g. persulphates, peracetates, chlorates, perchlorates, and iodine. However, preferred oxidants are lead tetraacetate, lead dioxide, or manganese dioxide.

[t is advisable in many cases, chiefly whenever inert polyenes are used, to add a Lewis acid, e.g. AlCl,, to the reaction mixture.

The reaction is carried out at normal pressure, at a temperature between l00C and +l00C, preferably between 50C and +50C, and in inert solvents or diluents, for example in halogenated alkanes, ketones, or ethers, but preferably in methylene chloride.

(III) formula [I by reaction of corresponding phenylisocyanates with carbazinic esters and subsequent cyclisation [Arch, Pharm. 294, 370 ff. (1961)].

The compounds of the formula I are suitable for combating a variety of animal and plant pests. They are suitable in particular for combating harmful insects. They can be used for example against insects which are harmful in the fields of hygiene, storage protection, and plant protection.

The insecticidal action can be substantially broadened and adapted to given circumstances by the addition of other insecticides and/or acaricides. Suitable additives include, for example: organic phosphorus compounds, nitrophenols, formamidines, ureas, carbamates, and chlorinated hydrocarbons.

The compounds of the formula I may be used as pure active substance or together with suitable carriers and- /or additives. Suitable carriers and additives can be solid or liquid and correspond to the substances conventionally used in formulation technique, for example natural or regenerated substances, solvents, dispersants, wetting agents, adhesives, thickeners, binders and/or fertilisers.

For application, the compounds of the formula I may be processed to dusts, emulsion concentrates granules, dispersions, sprays, to solutions, or suspensions, in the conventional formulation which is commonly employed in application technology.

The agents according to the invention are manufactured in known manner by intimately mixing and/or grinding active substances of the formula I with the suitable carriers, optionally with the addition of dispersants or solvents which are inert towards the active substances. The active substances may take, and be used in, the following forms:

Solid forms:

EXAMPLE 1 Manufacture of N-(4'-chlorophenyl)-2,3-diazabicyclo [2,2,1 ]hept-S-ene-Z,3-dicarboximide 6-6 g of freshly distilled cyclopentadiene are added at 8C to 21-15 g of 4-(p-chlorophenyl)-1,2,4-triazolidine-3,5-dione in 350 ml of absolute methylene chloride. While stirring, 44 g of lead tetraacetate dissolved in 350 ml of absolute methylene chloride are then added dropwise over the course of 4 hours and stirring is continued for 1 /2 hours at 0C. Undissolved substance is then filtered off and the solvent is evaporated at a bath temperature of 10C. The oily residue is well stirred with 200 ml of water. The water is then isolated from the crystalline product and the crystals are dried in the air. Recrystallisation from absolute methylene chloride yields the compound of the formula with a melting of 147C.

The following compounds are obtained in analogous manner:

After the solution had dried, each plant was populated with five Spodoptera caterpillars (3rd stage). A plastic cylinder was then slipped over the plant and sealed with a copper gauze cover. The mortality was determined after 2 days. In this test the compounds according to Example 1 exhibited good action against Spodoptera lirtoralis.

EXAMPLE 3 Insecticidal action against Leptinotarsa decemlineata 15 cm high potato plants were sprayed with a solution (acetone/water 1:1) containing 0.05% of active substance. After the solution had dried, each plant was populated with 10 Leptinotarsa larvae (3rd. stage). A plastic cylinder was slipped over the plant and sealed with a copper gauze cover. The mortality was determinated after 2 days.

In this test the compounds according to Example 1 exhibited good action against Leptinotarsa decemlineata.

EXAMPLE 4 Insecticidal action against Phyllodromia germanica A feed consisting of 6 parts of sugar, 6 parts of powdered milk, and l part of powdered egg was treated with a solution of the active substance in acetone so that the concentration of the active substance in the feed was 1%. After the feed had beenmixed the acetone was evaporated. Then feed, water, and freshly 6 hatched larvae were put into a jam jar. The mortality was determined after 10 days.

In this test the compounds according to Example 1 exhibited good action against Phyllodromia germam'ca.

EXAMPLE 5 insecticidal action against Tribolium castaneum 50 g of wheaten flour were mixed with a specific amount of a dust containing 5% of active substance so that the concentration was 0.01%. 25 beetles at a time were put into beakers containing 25 g of flour and 3 days later the flour was sieved. The eggs deposited in the flour constituted the infected material. The mortality was determined after 3 months.

in this test the compounds according to Example 1 exhibited good action against Tribolium castaneum.
